Description

Power through heavy-duty projects with the industrial strength of the TOKOMA 11mm High-Speed Steel (HSS) Drill Bit. Engineered for high-torque applications and deep penetration, this bit is designed to deliver clean, oversized holes in a variety of structural metals and dense plastics. It is the professional standard for automotive chassis work, structural steel fabrication, and heavy maintenance.

Industrial-Grade HSS Construction: Forged from premium High-Speed Steel to provide maximum thermal stability and edge retention. This ensures the bit maintains its cutting integrity even under the high friction levels generated when drilling large-diameter holes.

Substantial 11mm Diameter: The ideal heavy-duty size for clearing paths for M10 bolts, installing heavy-duty anchor fixings, and structural plate drilling.

Self-Centering 118° Split Point: Features a precision-ground tip that bites into the material instantly. This specialized geometry prevents the bit from “walking” or skating, ensuring total accuracy from the start without requiring a pilot hole in most materials.

High-Volume Parabolic Flutes: Engineered with wide, polished spiral flutes to facilitate the rapid ejection of heavy metal swarf. This prevents clogging, reduces heat buildup, and ensures a smooth, continuous drilling cycle.

Multi-Material Mastery: Optimized for high-performance drilling through mild steel, cast iron, aluminum, brass, copper, and thick structural plastics.

Standard Straight Shank: Designed for a secure, non-slip fit in all professional 13mm (1/2″) keyed or keyless drill chucks.

Tempered for Toughness: Professionally heat-treated to withstand the high mechanical stresses of large-bore drilling, significantly reducing the risk of fracture or bending.

Maximum penetration. Industrial durability. The definitive choice for heavy-duty metal drilling.
